Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami continued: After thus advising the demigods and pacifying mother earth, the very powerful Lord Brahma, who is the master of all other Prajapatis and is therefore known as Prajapati-pati, returned to his own abode, Brahmaloka.
